Glitter Volcano Lamp manufacturing process and characteristics
Glitter Volcano Lamp is composed of organic light-emitting diode OLED. Its light-emitting principle is similar to that of LED. It also uses the characteristics of the material to combine electrons and holes to emit light.
Because of its self-luminous characteristics, it does not require a backlight module and color filters, nor does it require the general TFT-LCD liquid crystal filling process. The glass substrate can be reduced from two to one, and the weight can be greatly reduced. Response speed, high brightness, wide viewing angle, full color and other characteristics.
Glitter Volcano Lamp bar screen consists of unit board, power supply, control card and connection.
The unit board is one of the core components of the LED display. The quality of the unit board directly affects the display effect. The unit board is composed of an LED module, a driver chip and a PCB circuit board. The LED module is actually a dot matrix encapsulated with resin or plastic by many LED light-emitting points.
The driver chip is mainly 74HC595 74HC245/244 74HC138 4953.
Glitter Volcano Lamp generally uses a switching power supply, 220V input, 5V DC output. It should be pointed out that since the LED display screen is a precision electronic device, a switching power supply must be used instead of a transformer. For a single red indoor 64x16 unit board, when it is fully lit, the current is 2A.
Strip screen control card, can control 1/16 scan 256x16 dots two-color screen, can assemble the most cost-effective LED screen. The control card is an asynchronous card, that is, the card can save information after power off, and can display the information stored in it without connecting to a PC.
Data lines, transmission lines, and power lines. The data line is used to connect the control card and the cable of the LED unit board, and the transmission line is used to connect the control card and the computer. The power cord is used to connect the power supply and the control card, the power supply and the LED unit board. The diameter of the copper core of the power cord connecting the unit board is not less than 1mm (mm).
Glitter Volcano Lamp product manufacturing process and characteristics
The production of LED upstream epitaxial chips accounts for about 70% of the manufacturing cost. The principle is to grow one or more single crystal layers on a substrate to form a chip containing a variety of chemical elements. The color and brightness of the light emitted are determined by the epitaxial material; In the midstream, the epitaxial chip is vapor-deposited with metal to make electrodes, which are etched and then cut and cracked into crystal grains; in the downstream, the chips are packaged to make various LED products such as indicator lights, digital displays and infrared emitters. And the product characteristics of LED, because its light-emitting principle is to apply a current to a compound semiconductor, through the combination of electrons and holes, and its excess energy is released in the form of light to achieve a luminous effect. Because its luminescence phenomenon is cold luminescence, so There is no need to warm up the lamp, and the life can be as long as 100,000 hours or more, and it has the advantages of small size, low power consumption, fast response speed and high reliability.
